Hi,

I'm having trouble understanding why A is correct.
If we look at A, and we first do the mathematical equation before printing, then why is B wrong?

Thanks for the help.

Explanation to option 1 says + is left associative. It does not say that mathematical equation has to be done first.
Since + is left associative, option 2 is incorrect.
This explains what is meant by associativity: http://en.wikipedia.org/wiki/Operator_associativity
Once you read the above link, it will be clear.

HTH,
Paul.

Thanks Paul!
